The capacity of the crackers extracts to scavenge DPPH radicals
(2, 2-diphenyl-1-picrylhydrazyl) was measured based on
the method described by Sanchez-Moreno et al. [13]. The
results obtained were expressed as the percentage inhibition
of DPPH based on the following formula:
Percent inhibition of DPPH ¼ ðAcontrol AsampleÞ=Acontrol 100
where Acontrol is the absorbance of the DPPH solution without
sample extract and Asample is the absorbance of the sample with
DPPH solution.
